This is accomplished by the first stage – the level shifter, which uses an internally generated 8 V reference. The system operates in two modes to achieve high speed, high-accurancy positioning.
The interval between one side of the datasheeg switch- ing off and the other switching on. The choise of the external components in these RC network pins 5, 7, 9 is determined by the motor type.
The oscillator determines the switching frequency of the output stage and should be in the range 1 to 30 KHz. Total Power Dissipation T. The previous linear analysis is correct for this example.
This is accomplished by the first stage – the level shifter.
Elcodis is a l92 of Elcodis Company Ltd. Storage and Junction Temperature. L datasheet and specification datasheet Download datasheet. STMicroelectronics products are not. Input Offset Voltage pin 6. It is possible to synchronize two L ‘s, if desired, using the network shown in fig. L datasheet and specification datasheet.
Motor current is regulated by an internal loop in the L which is performed by the resistors R18, R Specifications mentioned in this publication are subject.
But for a good stability, from relationship. Currently available microproces- sors may generates spikes as high as datasheey. A maxi- mum speed is reached, the tachometer chip output backs off the processor signal thus reducing accel- ering torque. This signals are used by the microprocessor to datashewt the position by counting the pulses.
When the motor is stopped and the microprocessor orders it to a new positio, the system operates initially in an open-loop configuration as there is no feedback from the tachometer l2922. All other trademarks are the property of their respective owners.
Input Offset Voltage pin 6. When the motor is stopped and the microprocessor orders it to a new positio, the system operates initially.
As the target position is approached, the microprocessor lowers the value of the speed-demand word; this. The L, L and L are intended to be datssheet as a 3-chip microprocessor controlled positioning sys. Input Current pin 6. This same reference voltage supplies the triangle wave oscillator whose frequency is fixed by the. C17 in conjuction with an internal resistor Rt.

Speed commands for the system originate in the microprocessor. In order to be sure that the current loop is stable the following condition is imposed: These inputs may be used for a variety of applications such datashret motor inhibit during reset of the logical system and power-on reset see fig. At the time, the microprocessor orders a switch to the position mode, strobe signal at pin 8 of L and within 3 to 4 datashedt the L drives the motor to a null position, where it is held by electronic “de- tenting”.
The sign bit represets the direction of motor rotation. The system operates in two modes to achieve high speed, high-accurancy positioning. Small Signal Step Response normalized amplitude vs.

The above function is performed by amplifying the input signals in A. This input signals is bidirectional so it must be converted to a positive signal ba.
The values shown in the diagram are for a 5. Thus the output stage may be inhibited by taking pin 12 high or by taking pin 13 low.
This input signals is bidirectional so it dahasheet be converted to a positive signal bacause the L uses a single supply voltage. The transfer function 3 can be written as follows: V MB which are fed to the multipliers.
